SDP-40

Basic Operation

STATUS MENU PARAMETER DESCRIPTIONS

2.0 ENCODING MATRIX, NONE

Indicates whether or not a matrix-encoded source is detected. When the parameter setting is MATRIX, a matrix-encoded source is detected. When the parameter setting is NONE, a matrix-encoded source is not detected. The SDP-40 cannot automatically detect matrix encoding in non-flagged input sources.

BIT RATE 32 to 640 kbps or 754 to 1509.7kbps

Indicates the rate at which the input signal is encoded. A higher bit rate indicates that less compression was used during the encoding process. Possible settings for Dolby Digital sources range from 32 to 640 kbps. Possible settings for dts(-ES) sources range from 754 to 1509.7kbps.

CENTER MIX LVL -3.0dB, -4.5dB, -6.0dB

Indicates the relative level of the center channel that was used during the mixing process.

CHANNELS 3/3.1, 3/2.1, 3/2, 3/1, 2/2, 2/1, 2/0, 1/0

Indicates the number of channels present in the input source. The first digit indicates the number of front channels present. The digit after the slash indicates the number of surround channels present. The digit after the decimal point indicates the presence of LFE (low- frequency effects) information. For instance, if the parameter setting is 3/2.1, an input source with three front channels, two surround channels, and LFE information is present.

Possible settings for Dolby Digital sources include 3/2.1, 3/2, 3/1, 2/2, 2/1, 2/0, and 1/0. Current settings for dts(-ES) sources include 3/3.1 and 3/2.1.

DIALOG OFFSET -27 to +4dB

Indicates the dialog normalization value applied to the input signal. Dolby Digital sources reproduce dialog at 27 decibels below full- scale (-27dBFS). When the dialog normalization value of the incoming signal is higher or lower, the DIALOG OFFSET parameter indicates the amount of adjustment the SDP-40 makes to normalize dialog to -27dBFS.

ES ENCODING DISCRETE, MATRIX, OFF

Indicates whether or not a dts-ES-encoded source is detected. When the parameter setting is DISCRETE, a discrete 6.1-channel dts-ES source is detected. When the parameter setting is MATRIX, a 5.1-channel dts-ES source with a surround-encoded back channel is detected. When the parameter setting is NONE, a standard dts source with no dts-ES encoding is detected.

EX ENCODING MATRIX, NONE

Indicates whether or not a Dolby Digital Surround EX-encoded source is detected. When the parameter setting is MATRIX, a 5.1-channel Dolby Digital source recorded with Dolby Digital Surround EX-encoding is detected. When the parameter setting is NONE, a standard 5.1-channel Dolby Digital source recorded without Dolby Digital Surround EX-encoding is detected. The SDP-40 cannot automatically detect Dolby Digital Surround EX encoding in non-flagged input sources.
